Effect of different cross-fostering times on the plasma parameters of piglets.
| Plasma Parameters | NC-F1 | C-F1 | C-F2 | SEM | p-Value |
|---|---|---|---|---|---|
| GH (ng/mL) | 1.99 | 1.90 | 1.87 | 0.13 | 0.93 |
| COR (ng/mL) | 14.08 a | 15.52 a | 17.44 b | 0.56 | 0.03 |
| α-AMY (U/dL) | 153.12 | 148.71 | 150.85 | 5.90 | 0.96 |
| IgA (g/L) | 1.04 | 1.01 | 0.92 | 0.03 | 0.36 |
| IgG (g/L) | 9.31 | 9.52 | 9.46 | 0.16 | 0.87 |
| IgM (g/L) | 0.86 | 0.83 | 0.77 | 0.03 | 0.50 |
GH—growth hormone; COR—cortisol; α-AMY—alpha-amylase; IgA—immunoglobulin A; IgG—immunoglobulin G; IgM—immunoglobulin M; NC-F1—not cross-fostered, N (NC-F1) = 6, N means the number of piglets per group; C-F1—cross-fostered at 36–48 h after birth, N (C-F1) = 6; C-F2—cross-fostered at 7 day after birth, N (C-F2) = 6; SEM—standard error of mean; a, b—Values with different superscripts differ significantly (p < 0.05) among different treatments (rows).
